Abstract

Cumulative time base error on real time clocks (RTC) with receiver units can be practically eliminated us- ing a simple group transmission. This feature can be activated by sending out minimal data (address only) for a reseuroundoff feature or address and data for a time setting feature. The reset feature, depending on the customer/system parameters, would round off seconds, minutes and/or hours upon receipt of the correlation signal. Depending on the accuracy of the RTC, the base station could send out as many correlation signals as required for a specified cumulative time base error.
